BackgroundSeveral studies have shown that serum IL-10, IFNγ and MIF are elevated in patients in severe dengue (SD) and could be used as potential biomarkers. We proceeded to determine if these cytokines could be used as biomarkers in a large cohort of adult dengue patients with varying severity of dengue infection.MethodsSerum IL-10 levels were determined in 259 of whom 40 had severe dengue infection. Serum IFNγ and IFNα levels were done in 78 and MIF levels were done in 65 patients with acute dengue infection. Clinical features and laboratory investigations were undertaken during the febrile and critical phase.ResultsWe found that serum IL-10 levels were significantly higher (p = 0.001) in patients with SD, when compared to those with non SD. Serum IL-10 levels significantly and inversely correlated with white cell counts (R = −0.23, p = 0.0002) and lymphocyte counts (R = −0.29, p < 0.0001) but significantly and positively correlated with aspartate tranaminase levels (R = 0.16, p = 0.01) and alanine transaminase levels (R = 0.22, p = 0.007). However, IL-10 levels did not have a good predictive value in discriminating those who were likely to develop SD (AUC = 0.66). Serum IFNγ levels were also significantly higher (p = 0.04) in patients with SD when compared to non SD. There was no difference (p = 0.34) in serum IFNα levels and serum MIF levels (p = 0.15) in patients with SD and non SD.ConclusionAlthough serum IL-10 was significantly elevated in patients with SD it had a poor discriminatory value in identifying those with SD and non SD and therefore, is unsuitable to be used as a robust biomarker in this cohort.
The formation of the IPI analytics system to support a community of hospitals has been successful in providing sophisticated tools for member facilities to review, investigate, and efficiently analyze smart-pump alert data, not only within a member facility but also across other member facilities, to further enhance smart pump drug library design.
The National Zoological Garden plays a vital role in conservation of reptiles in Sri Lanka. Since parasitic infestations of captive reptiles can impact their health, a survey for intestinal parasites and ectoparasites was conducted on 19 selected reptilian species (14 snakes, four chelonians, and one crocodilian) housed at the National Zoological Garden, Sri Lanka. Of the reptiles screened, 62% (N = 139) were infected with parasites; 66% and 24% exclusively harbored intestinal and ecto parasites, respectively, while 10% carried both types of parasites. Three ticks (Ixodidae), two adult cestodes, plerocercoid larvae, and four nematode species were recovered during this survey. Three types of nematode ova and a single type of digenian ova, protozoan cysts, L3 nematode larvae, and a protozoan were detected in the feces. In this first systematic survey of reptilian parasites in Sri Lanka, four new host-parasite records are documented.
BackgroundPrimary polydipsia is commonly seen in patients with psychiatric illnesses. Excess water intake is also seen in patient with anorexia and anticholinergic medications. We report a patient who had hyponatraemia and rhabdomyolysis after consuming excess water for ureteric calculus.Case presentationA healthy middle-aged male presented with an episode of generalized tonic-clonic seizure and reduced level of consciousness preceded by consumption of excess water. He was recently diagnosed to have a ureteric calculus and was advised to consume plenty of water. On examination, he was disoriented in place, person and time. Except for the generalized diminished reflexes, other neurological and systemic examinations were normal. He had severe hyponatraemia, mild hypokalaemia and myoglobulinuria. His serum creatinine phosphokinase and aspartate aminotransferase were markedly elevated. The diagnosis of rhabdomyolysis in the setting of acute water intoxication was made. Optimum fluid and electrolyte management achieved a dramatic recovery of consciousness, hyponatraemia and rhabdomyolysis.DiscussionThe patient has had excess water intake due to a compulsive act in the background fear of ureteric calculus. Such act could lead to severe hyponatraemia and rhabdomyolysis. Therefore, future similar acts could be prevented by proper medical advice. Further, emergency physicians should be vigilant for rhabdomyolysis in patients with hyponatraemia or hypokalaemia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
